MEASURING INSTRUMENT.

Be it known thatI, GAYLE 'H QBA E a citizen of the United States, and resident of Shamrock, in the county of Greek and State of Oklahoma, have invented certain new and useful Improvements in 'Measuring Inst-ruments', Of'WlliCll the following is a specification.

The present invention relates to new and useful improvements in measuring devices and has particular reference to an improved type" of depth measuring. device. for wellsandthe like. I I

The primary object of my inventionis'to' provide a well measuring device ofthe class. described which maybe quickly and easily attached to the ,bailer rope of the well pumping mechanism: whereby to indicate the depth of the well; At the present time in measuring thefdepth of oil wells and the like itis necessary that'pumping operatlon cease for a considerable-time while the meas uring process is being carried on. Not only this, but the, depth measuring devices now employed are cumbersome and ineificient as Well as; naccurate manycases. It is therefore, a further object .of my invention to providea simple andlightly; yet durably constructed measuring device "which may be; attached to the bailer'rope or pump rod as the case maybe to indicate the amount of cable or rope which "is paid out by the op erator. I I v A stillfurther object of my invention: is to provide a. measuring device of the class described having improved means for fastening" the same in operative e11- gagement with a cable or rope, the motion of the rope being transmitted to the-measur ingvmechanism by friction, i

A still further obj ect of my invention is to provide improved means for maintaining ythel gui'ding meansin engagement with such rope.

Of course,' I do notlimitmyself to the use of the device as a well measuring article,inviewv of the fact that the same, without Ina-1. terialm di-fications; may be :used in various. capacities. 1

Otherobjects and advantages to be derived from the use of"'my:i mprov ed depth measuring device will appear from the fol lowing detail description and the claims, taken in connection with the accompanying drawings, inwhich Figure 1 is a side elev ational 'vievgpf a,

measuring device embodying the improvements of my invention;

Fig. 2 is a top plan view of the same a portion thereof beingfibroken away and in section; I

Fig, 3 :is a longitudinal sectional view takenv on the line 3-3 of Fig. 2 looking in the direction ofthe arrows;

Fig. 4 is a vertical'sectional view taken lthrough the measuring member of my invention on the line of Fig. 3; and

F 5 is enlarged ffragmentaryperspective -v1ew1 of an improved fastening;

means which employ inconnection with my nvention.

Referring more particularly to the draw-y lngs wherem slmllar characters of reference designate like and corresponding parts throughout the various views,- I haveprovided a frame composed of two hingedlyconnecte'dsections l and 2,. said sections be-. ing formed 'ofspaced parallel portions 3.

, and, respectively, in which are journaled 1 power receiving friction wheels 5 and 6.

The sectionsl and 2 of theframe mentioned arevconn ecte d hingedlyiasat 7 L The wheel shaft 8 on the free endof which is mounted a worm 9a purpose'which will hereinafterappear. I I v I provide means for maintaining the wheels "5 and. 6 in frictional engagement with a rope or other element thelength, of which 1s to be determined saidmeans com-j prising a pair of coiled springs 10 and 11;. arranged on opposite sides of the frame.- The" spring ,10 is permanently fastened in the bracket=12 carriedvby the sections land I 2 as best shown in Fig. 2, and provides means for retaining. the-sectlons in open position I when the lever .83 has released the spring 11: The spring 11' ispermanently v fastenedat 13 to a bracketle carried by the section 2, the free end of the spring being retained in detachable connection with the section lby means of an improved fastener carry the wheel 6, whichis normally-held in I close proximity to wheel 5 by the tension of the springs, 10 and 11. The "measuring-- means of my invention includes a motion receiving-shaft 16 arrangedwith one free end thereof within the housing 17 and the other free end thereofadjacent the worm 9, the latter mentioned free end having a worm gear 18 thereon, for meshing engagement with the worm 9. The inner free end of said shaft 16 is provided with a worm 19 the intermediate portion of said shaft being mounted in a bearing 20. The worm 19 is arranged in meshing engagement with a relatively large worm gear 21 mounted on a transversely arranged shaft'22 carried in the housing 17. The shaft 22 extends through the casing, one face'23 of said casing being provided with a dial 2 1 over which is movable an indicating hand 24: carried by said shaft 22. A gear 25 -mounted on the shaft 22 meshes with a relatively larger gear 26 carried on a supplemental shaft 27 a pinion 28 mounted on said shaft meshing with a relatively large gear 29'carried by a hollow shaft 30 through which said shaft 22 operates. On the free end of the hollow shaft 30 I provide a second indicating hand 31 cooperating with the first mentioned indicating hand. One of the hands is adapted to indicate in tens and the other hand in hundredsor some similar relationship.

The fastening means referred to previously for connecting the spring 11 to the section 1 of the frame comprises a'lever 33 carried by the free end of said spring 11, said lever having a finger engaging portion 84 and bifurcated as at 85 to provide spaced arms 36 for engagement with spacedextensions 37 formed on one of the'sides 3- of the section 1 of the frame. In use the member 33- is adapted to be engaged behind the extensions 37 retaining the spring in connection with the section 1 fora purpose which will hereinafter appear.

In operation the hinged sections 1 and 2 are opened in order to embrace a cable or the like,'said cable being arranged between the wheels 5 and 6. The fastenlng member 33 is connected with the section 1 and this maintains the springs under tension. Such tension brings the friction wheels 5 and 6 into snug engagement with the cable or rope and any-movement of the cable or rope will therefore be imparted to said wheels. Such motion is transmitted to the registering mechanism contained in the housing 17 by virtue of the worm 9 and worm gear 18.

It will thus be seen that by attaching my improved measuring device to a well pumping cable or the like the eziact length paid out by the operator may be accurately and quickly determined. A

Of course, it will be readily apparent that the device of my invention may be applied to different uses and therefore, need not be used wholly in connection with measurin thedepth of wells or the like.

From the above description taken in con- 'nectio'n -with the accompanying drawing, it

is thought that a clear andcomprehensive understanding of the construction, operation and advantages of my invention may be had, and while I have shown and described my invention as embodying a specific structure,

tion, what I claim as new and desireto secure by Letters Patent, is
